Doubt regarding a formula withSET ANALYSIS OR AGGR

[#1]

Hi

I don't know if my problem have to be solved with what option: i have to count the number of invoices that in the total have 3 units or less units invoiced.

I had tried with these 2 options but for some reason they don't work. On the other hand I don't know which is the best option of them to solve this problem, could you explain why???

the formulas that I wrote are these:

formula 1: Count(AGGR(SUM([UN VENDIDAS])<=3, NUM.FACTURA)) - this formula is not working well because its counting the invoices that have lines with 3 or less units instead of just counting the invoices that have 3 or less units in the total.

formula 2: Count({< Sum ([UN VENDIDAS])<=3 >} DISTINCT NUM.FACTURA) - this formula is showing error in the syntaxis

Thanks for your help

Hi once again

im trying with this formula to discard 0 records but its not working:

Count({< [NUM.FACTURA] = {'=Sum([UN VENDIDAS])= {1,2,3}'} >} DISTINCT  [NUM.FACTURA])

what should i change???

thanks for your comments

That won't work because How Sum([UN VENDIDAS]) has the values are 1,2,3

You mean to say this?

Count({< [NUM.FACTURA] = {'=Sum([UN VENDIDAS])= {1 or 2 or 3}'} >} DISTINCT  [NUM.FACTURA])

Hi Anil

Sorry for not answering before,.,.,I had tried your solution however it dont work. On the other hand i have a question: if  i would want consider a bigger range I had saw many options with this kind of script

Count({< [NUM.FACTURA] = {'=Sum([UN VENDIDAS])= {">0","<=3"}'} >} DISTINCT  [NUM.FACTURA])

do you know why its not working?

thanks for your help

You can do this:

Count({<[NUM.FACTURA] = {"=Sum([UN VENDIDAS]) > 0 and Sum([UN VENDIDAS]) <= 3"} >} DISTINCT  [NUM.FACTURA])

[Anil_Babu_Samineni]

Ranges should be syntax as follow

Count({< [NUM.FACTURA] = {'=Sum([UN VENDIDAS])= {">0 <=3"}'} >} DISTINCT  [NUM.FACTURA])

Thanks a lot Sunny, your solution worked perfectly. now i see that a "problem" in Qlikview could have many approaches however im still dont understand why one solution could work with some context and in other context dont.

I think a good place to start for set analysis would be this

A Primer on Set Analysis

and also read this:

Set Analysis: syntaxes, examples

Syntax isn't right pedro... I am not sure what the idea was behind Anil's expression, but it isn't the right way to code it
